Abstract

The invention discloses a low-profile high-efficiency dual-linearly polarized antenna array, and belongs to the technical field of antennas. The low-profile high-efficiency dual-linearly polarized antenna array comprises an antenna sub-array part and a waveguide feed network part from top to bottom, and the antenna sub-array layer is composed of 8 antenna sub-arrays in total of 2 * 4. And a waveguide coaxial conversion structure for realizing vertical interconnection of the antenna sub-array part and the waveguide feed network part is arranged between the antenna subarray part and the waveguide feed network part. Two feed forms of strip lines and waveguides are integrated in the whole array, strip line feed forms are adopted in antenna sub-arrays, waveguide feed forms are adopted among thesub-arrays, each feed form is composed of two sets of feed networks, and vertical and horizontal polarization radiation characteristics of the whole array are respectively realized. And the branch end of the waveguide feed network is vertically interconnected with the combining end of the strip line feed network in the subarray through a waveguide coaxial conversion structure. According to the invention, the characteristics of low profile, high efficiency and dual linear polarization of the whole array are realized.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a low-profile high-efficiency dual-linearly polarized antenna array. Background technique [0002] With the rapid development of the mobile communication field, the demand for simultaneous vertical polarization and horizontal polarization is becoming more and more urgent. At the same time, the requirements for portable, compact, low-profile and high-efficiency transceiver terminals are also getting higher and higher. Traditional parabolic antennas and waveguide slot arrays are difficult to meet the above requirements. [0003] The microstrip antenna array has technical characteristics such as low profile, easy integration, and compact structure. It can be easily arranged on the surface of equipment, and can conform to the surface of missiles, aircraft and other carriers. Devices are integrated in blocks. In the past two years, microstrip antennas have been more and more widely...
